Key Responsibilities: Claims Submission: Prepare and submit clean claims for ABA, speech, and OT services to commercial payers and Medicaid; verify CPT codes, modifiers, units, and documentation before submission. Working knowledge of CPT/ICD-10 coding, modifiers, and payer-specific billing rules; familiarity with BCBSM, Blue Care Network, HAP, UHC/Optum, Priority Health, and Michigan Medicaid is a strong plus.
